What does DISODIUM LAURETH SULFOSUCCINATE do in a formulation?

Its primary functions are:

• Cleansing
• Foaming
• Surfactant
• Foam Boosting

Additional notable properties include reducing the skin-irritating effects of other surfactants like Sodium Laureth Sulfate (SLES), acting as a hydrotrope (stabilizing clear formulas), and dispersing calcium soap.

Safety Profile:

· General Assessment: Recognized as safe for cosmetic use when formulated to be non-irritating. Its large molecular size prevents skin penetration.

· Safety Guidelines: The Cosmetic Ingredient Review (CIR) Expert Panel concluded it is safe in current use concentrations, typically between 0.06% to 2% for leave-on and 0.4% to 10% for rinse-off products. It should not exceed 1% in products for prolonged skin contact.

· Important Note: As an ethoxylated ingredient, it may contain trace amounts of 1,4-dioxane, which is minimized through purification during manufacturing
